THREE WAY SA FsPECIPICATION forming part of Letters Patent N0. 378.519,dated February 28, 1888.

Application filed JulyfZQ, 1887.

.To allwhom it may concern.-

Beitknown that we,WrLLrAM F. D. PASCOE and J AMES WILsoN RAUB, citizensof the United States, residing atSouthEaston, in the county ofNorthampton and State of Pennsylvania, have invented a new and usefulImprovement in Threeay Safety'Switches, of which the following is aspecification.

Our invention relates to an improvement in three-way safety-switches;and it consists in the peculiar construction and combination of devices,which will be fully set forth hereinafter,and particularly pointed outinthe claims.

In the accompanying drawings, Figure 1 is a top plan view of a switchembodying our improvements, showing the same set for the main track.Fig. 2 is avertical sectional view taken on the line as m of Fig. 1.Fig. 3 is a similar View taken on the line y y of Fig. 1. Fig. 4 is adetached perspective view of one of the connecting-rods.

A represents the main track, and B represent side tracks, which extendfrom the opposite sides of the main track.

D and I) represent rails which bend at a suitable angle and have theirstraight portions arranged in line with and formingapa rt of the maintrack, their diverging portions arranged in line with and formingportions of the outside rails of the side tracks, B and C, respectively.

E and E represent pointswitch-rails, which are pivotally connected torails A of themain track and have their free pointed ends arranged onthe inner sides of the diverging portions of the rails D and D.

F and Farepoint switch-rails pivotal] y con nected to the rails formingthe inner side of the side tracks, the said rails F and F being arrangedon the inner sides of the rails E and E, as shown. The rails F and E areconnectcd together near their free ends by con ncctingrods G. The saidconnecting-rods are each formed of three sections, 9, g, and 9 which arepivotally connected together by means of bolts 5 The inner ends of thesec tions 1 are bifurcated, as at 9 and embrace the upper and lowersides of the horizontal flange f on the inner side of the rail F, at thebase thereof, and are secured to the said flange by bolts. The centralportions of the sections Serial No. 245,004. (No model.)

9 are oblique, and the ends of the said sections, which extend inopposite directions from the ends of the oblique portions, are parallel,but are out of line with each other. The inner ends of the sections 9are bifurcated, so as to receive the opposing ends of the sections atthe pivotal connection therewith. The outer sections, extend under thebase of the rails F, E, and D. On the upper sides of the outer ends ofthe said sections are blocks and on the upper sides of said blocks arearranged the outer ends of bracket-arms g. Bolts connect the sections 9blocks 9 and bracketarms rigidly together. Said bracket-arms extendinward from the blocks, pass through horizontal transverse openings madein the web of the rail D, and the extreme inner ends of the saidbracket-arms are upturn-ed and broadened to form plates g, which bearagainst the outer sides of the web of the switclrrail E and are boltedrigidly thereto.

From the foregoing description it will be understood that theswitch-rails F and E will be caused to move simultaneously.

H represents connectingrods which are similar in construction to theconnectingrods G, and have their oblique portions arranged transverselyover the oblique portions of the rods G, the said rods H connecting theswitchrails E and F and having their bracket-arms passed throughhorizontal transverse openings in the web of rail D. A series ofconnectingrods, 1, which are similar in construction to the rods G, withthe exception that the central sections thereof are straight, areemployed to connect the rails E and F at suitable regular distances,thus serving to strengthen the connections between the saidswitch-rails, and similar rods, K, connect the switch-rails F and E.

L represents series of bearingplates which are secured on the uppersides of the crossties and are arranged under the base of the switchrails. The outer ends of the said plates are upturned to form verticalflanges M.

N represents supporting-chairs, which are bolted to the outer ends ofthe plates L, and are provided. with inwardly-projecting bracket-arms N,that bear against the outer sides of rco the rails D and D and serve toprotect thelatter against lateral displacement under strain.

On opposite sides of the track are erected the usual switch targets orsignals, 0 and O. The target 0 has a crank-arm which is connected to oneof the connecting-rods II, and the target 0 has a crank-arm which isattached to one of the rods G. The said targets are thereby rotatedthrough a quarter of a circle when the switch-rails are moved in eitherdirection, and thus indicate to the engineer of an approaching train theposition of the switch.

Prepresentsaseries of segment-plates which are connected together bymeans of bolts R. The outer plates of the said series haveoutwardly-projecting base-plates S, which are secured on the projectingends of two of the crossties. In between the segment-plates are pivoteda pair of operating hand-levers, T and T. The lower end of the lever Tis connected to one of the-rods G by means of the rod t, which is formedof two sections connected by a swivel, t, and the lower end of the leverT is connected to one of the connecting-rods H by means of a similarrod, 25 Each of the hand-levers has a spring-actuated latchet-boltadapted to engage notches in the peripheries in the segmentplates, andthereby secure the hand-levers in any desired position. The hand-leverT,being connected to the rods G, is adapted to operate the switch-railsEand E, and thereby set the switch either in line with the main track orwith the side track 0, and the handlever T, being connected to theswitch-rails E and F, is adapted to set the switch either in line withthe main track or with the side track B.

Having thus described our invention, we claim- 1. The combination of therigid main rails, the movable switch-rails, and the arms rigidly securedthereto and projecting outward through openings in the webs of theadjacent main rails, and the bars passing under the bases of the mainrails and connecting the projecting arms of each switch-rail to itscompanion switch-rail, substantially as described.

2. In a railwayswitch, the combination of the switch-rails and thejointed bars connecting the said switch-rails, the said bars passingunder the bases of the main rails and having the inwardly-extending armspassed through openings in the webs of the main rails, substantially asdescribed.

3. The combination of the rigid main rails, the movable switch-rails,the arms rigidly secured to the switch rails and projecting throughopenings in the adjacent main rails, and thepivotally-jointedconnecting-bars passing under the bases of the main rails and havingtheir end sections rigidly secured to the projecting arms of theswitch-rails and to the base-flanges of their companion switch-rails,substantially as described.

4. In a three-way railway-switch, the combination of the rigid divergingrails D and D, the point switch-rails E E and F F, and the barsconnecting the said switch-rails together in pairs, the said bars beingeach composed of a series of sections pivotally jointed together, havingtheir inner ends provided with bracketplates rigidly bolted to theflanges on the innor sides of the inner switch-rails, and their outerends passed under the bases of the opposite rigid and switch rails, andprovided at their outer ends with inwardly-extending extension-armspassed through openings in the webs of the rigid rails and rigidlyconnected to the outer sides of the webs of their companionswitch-rails, substantially as described.

5. In a three-throw railway-switch,the combination of the main rails DD, the switchrails E E F F, the pivotally-jointed bars H, connectingwith the switchrails F at one end, then passing under the bases of theopposite switch and rigid rails, and having inwardlyextending arms toconnect with the rails E, and the jointed bars G, arranged in a similarmanner, but connecting the rails F E, the said bars G H being crossed,and the straight jointed bars K I, connecting the switch-rails in amanner similar to the arrangement of the bars G H, as set forth.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
